Product Description:

The KSM01.2B-071C-25N-M1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining the control electronics and power stage inside the motor housing, it supports decentralized automation layouts that reduce cabinet use and shorten cable runs. The unit provides torque, position, and velocity control for packaging, material-handling, and assembly equipment that depends on compact installation and responsive feedback. With the inverter mounted directly on the motor, drive functionality can be placed close to the load so the machine layout stays compact and external wiring remains easier to route.

Electrical energy reaches the unit through a single Hybrid Connector that carries power, logic, and feedback through one sealed interface, which simplifies wiring and reduces external connection points. The drive operates from a DC 750 V bus, and heat is removed by natural convection, so the mounting position must leave enough free space for airflow around the housing. Commands and diagnostics are exchanged through SERCOS 2 (RS422) for coordinated multi-axis operation, while rotor position is transmitted over a Hiperface link. The optical encoder provides 128 signal periods per revolution, allowing fine interpolation for stable motion control. This arrangement keeps the electrical interface compact while supporting the timing accuracy expected in synchronized servo applications.

The feedback system uses a Multi-turn absolute reference, so the axis can retain position information through power interruptions without requiring a homing cycle at restart. Mechanical power is transmitted through a shaft with a keyway, which supports rigid coupling to pulleys or gearboxes. Within the envelope of frame size 071 and length code C, the standard version 2 design operates without a holding brake and uses an internal shaft seal to help keep dust and light splashing away from internal components. It also carries a basic performance level and omits integrated safety functions, keeping the feature set focused on core servo operation.
